Send a sub parameter in an API call

I have a basic API question. :slight_smile: I want to use a PATCH API call sending this payload:

{
“notifications”: {
“send_contact_message_emails”: false
}
}

How do I send this “sub parameter” send_contact_message_emails? Putting it as a normal parameter does not work. I also tried putting the payload above into the body of the call. No luck there either. What am I missing?

Cheers, Peter

Use the json setup body via plain text rather than add parameter button

Thanks @chris.williamson1996 for coming back. I tried the body thing:
